1) In modern packet-switched networks, including the Internet, the source host segments long application-layer messages (for example, an image or a music file) into smaller packets and sends the packets into the network. The receiver then reassembles the packets back into the original message. We refer to this process as message segmentation. For this exercise we will use the network architecture provided in the figure below, were Rs, Rc and R,for i 11,2,3,4), the transmission rates of the server link, client link and intermediate network links. Consider a message that is 60 106 bits long that is to be sent from client to server. Ignore propagation, queuing, and processing delays. Client Server R2 Re R. R, R
